hi,
sending cleanup/move of shadow counters. I need it
for my other changes of stat scripting, but I think
it can stand alone as a cleanup.
Also in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/shadow
I tested on Haswel with limited set of transaction events,
but all seemed ok.
thanks,
jirka

Adding a way to tag an evsel object with ID value based
on its name. It will be used for transaction events,
but could be useful for others.
This way we can identify transactions events and get rid
of the current position based way we use.

instead of current possition based way.

We can use already existing parse_events interface.
Both transaction_attrs and transaction_limited_attrs are
changed to be single strings.

It's no longer needed, because we use nameid to recognize
transaction events.
Keeping it only in stat code to initialize transaction events.

For what? Can you ellaborate? Just by looking at this commit message I

Separating shadow counters code into separate object
as a cleanup, but mainly for upcomming changes, so
could use it from script command context.
